Dominant seventh chord in the major scale contains diminished triad of the seventh?
The seventh chord built on the fifth step of the scale (the dominant seventh) is the only dominant seventh chord available in the major scale: it contains all three notes of the diminished triad of the seventh and is frequently used as a stronger substitute for it.
What does this mean?
Especially "diminished triad of the seventh"?

"Dominant seventh" is a shorthand for what others call a "major-minor seventh," meaning a major triad with a minor seventh on top.
If we take all notes of a major scale and create seventh chords on top of them using only the notes of that major scale, only one of these seventh chords will be a major-minor ("dominant") seventh: that built on scale-degree 5 of the major scale. Scale-degree 5 is called the "dominant," hence the term "dominant seventh."
When this text says "diminished triad of the seventh," the writer is being a little loose with their terminology. It should say "diminished triad of the seventh scale degree," because the triad built on top of that seventh scale degree is a diminished triad. And that same diminished triad is the third, fifth, and seventh of the dominant seventh chord built on scale-degree 5.
In C major, scale-degree 5 is G and scale-degree 7 is B. The seventh chord on G is G B D F (a major triad G B D with a minor seventh G F), and it includes the diminished triad built on scale-degree 7: B D F.

We call the resolution stronger because the V7 chord is much more directional (the vii°7 chord, which would be the diminished seventh chord, is symmetrical and ambiguous). There are other reasons, and as further reading, this post does a good job explaining this resolution's strengths.

In C major, scale-degree 5 is G and scale-degree 7 is B. The seventh chord on G is G B D F (a major triad G B D with a minor seventh G F), and it includes the diminished triad built on scale-degree 7: B D F.
